- UltraSafe design
- Compact enough for a glovebox or trunk pocket
Cons
- Lower peak amps than the big-engine picks

The GOOLOO A3 combines a 12V, 3000A jump starter with an air compressor, so one box covers a dead battery and a low tire. If you'd rather carry one roadside gadget than two, start here.
Pros
- Jump starter and air compressor in one unit
- 3000A rating
- Replaces a separate inflator
Cons
- Bulkier than a jump-only pack

The OXILAM is the highest-amp pack on this list at 6000A, listed for all gas engines and diesels up to 12L. It doubles as a USB and Type-C power bank and has an LED display and light. Choose it when the vehicle is big or the winters are cold.

Check price on AmazonBattery Tender Junior
If your car dies because it sits for weeks, a jump pack treats the symptom. The Battery Tender Junior is a maintainer that keeps a parked battery topped up, so you don't need the jump in the first place. It's ideal for a weekend car, a motorcycle, or a car parked over the winter.
Pros
- Prevents a dead battery on a car that sits
- Inexpensive
- Simple to leave connected in a garage
Cons
- Needs an outlet; it can't jump a car on the roadside
Best for: Weekend cars, motorcycles, and winter storage.
Check price on AmazonHow to choose
- Match the pack to the engine
- Small cars are fine with a pack like the 1000A NOCO GB40. Trucks, big SUVs, and diesels should look at packs rated for their engine size, like the S ZEVZO ET03 or OXILAM.
- Safety features
- Look for clamp protection against reverse polarity and sparks. A name-brand pack like NOCO is the safe default if you're unsure.
- Extras worth having
- A built-in air compressor (GOOLOO A3), a USB power bank, or a work light make a pack more useful between dead batteries.
- Keep it charged
- A jump pack only helps if it's charged. Top it up every few months and after each use.
Our shortlist
Most drivers should get the NOCO Boost GB40. If you want a tire inflator too, the GOOLOO A3 combines both. For trucks and diesels, choose the S ZEVZO ET03 or the higher-rated OXILAM. If your battery dies because the car sits, buy the Battery Tender Junior instead.
Frequently asked questions
How many amps do I need in a jump starter?
It depends on the engine. Check the pack's listed engine sizes: for example, the S ZEVZO ET03 is rated for up to 8.0L gas and 7.0L diesel, and the OXILAM lists all gas engines and up to 12L diesel.
Jump starter or battery maintainer?
A jump starter rescues a dead battery anywhere. A maintainer like the Battery Tender Junior plugs into an outlet to keep a parked car's battery from dying. Many people with a weekend car want both.
